local-exec Provisioner

The local-exec provisioner invokes a local executable after a resource is created. This invokes a process on the machine running Terraform, not on the resource. See the remote-exec provisioner to run commands on the resource.

Note that even though the resource will be fully created when the provisioner is run, there is no guarantee that it will be in an operable state - for example system services such as sshd may not be started yet on compute resources.

Example usage

# Join the newly created machine to our Consul cluster
resource "aws_instance" "web" {
    ...
    provisioner "local-exec" {
        command = "echo ${aws_instance.web.private_ip} >> private_ips.txt"
    }
}

Argument Reference

• command - (Required) This is the command to execute. It can be provided as a relative path to the current working directory or as an absolute path. It is evaluated in a shell, and can use environment variables or Terraform variables.
